Abstract
A method for operating a radar sensing system includes configuring a transmitter to transmit a radio signal. A receiver is configured to receive radio signals. The received radio signals include the transmitted radio signal transmitted by the transmitter and reflected from objects in the environment. The method includes with advanced temporal knowledge of the codes used to modulate the transmitted radio signal, using code values of the plurality of codes, and in combination with a bank of digital finite impulse response (FIR) filters, generating complementary signals of any self-interference noise. The method further includes subtracting the complementary signals at one or more points in the receiver prior to the interference desensing the receiver. The radar sensing system further includes a frequency modulated continuous wave (FMCW) interference canceller for detecting the largest interference signals and sequentially cancelling them while signal processing the received radio signals.
